The present invention further provides a supplementary description of the data transmission method provided in the above embodiment.
As shown in fig. 2, a flow chart of steps of another embodiment of a data transmission method of the present invention is shown, and the data transmission method includes:
s201, acquiring service parameters of a plurality of distribution servers and service states of terminals;
wherein, the service parameters at least comprise: time consumed for sending the data packet, queue cache data size, address information of the distribution server, port information, the state of the current service, memory consumed information of the distribution server, bandwidth consumption information, the current service concurrency number and the maximum concurrency number.
S202, if the time consumed for sending the data packet in the service parameters of the distribution server is judged to be longer than a first preset value and/or the size of the queue cache data is judged to be larger than a second preset value, the distribution server is determined to be in a blocking state.
Specifically, after the distribution server is connected with the terminal, the server monitoring platform monitors the service information of the distribution server in real time, and when the service information of the distribution server is in a blocking state, the distribution server is switched to ensure normal transmission of terminal data;
the first preset value and the second preset value can be set according to requirements.
Illustratively, as an optional implementation manner, the time taken for sending the data packet in the service parameter in the distribution server is 10ms, which is greater than the first preset value of 8ms, and this indicates that the distribution server is in a blocking state.
As another optional embodiment, in the process of sending the monitoring data to the terminal, the server monitoring platform determines that the distribution server is in a blocking state according to that the size of the queue cache data of the monitoring data in the service parameters is 12M and is greater than the second preset value by 10M.

And S203, if the distribution server is blocked, switching the distribution server so that the distribution server and the terminal transmit the service data.
The server monitoring platform acquires service information of each distribution server, wherein the service information comprises blocking or idle, the service information can be determined according to the CPU occupancy rate or the memory utilization rate of each distribution server, if the CPU occupancy rate is greater than a first preset value and/or the memory utilization rate is greater than a second preset value, the distribution server is determined to be in a busy state, otherwise, the distribution server is in an idle state.
When the server monitoring platform distributes the distribution servers, the distribution server with the congestion is switched to an idle distribution server according to a preset distribution server list, for example, the distribution server in an idle state may be selected, for example, an idle distribution server may be selected randomly, or the distribution servers may be selected according to the sequence of the distribution servers, or each distribution server may be sorted according to the occupancy rate of the CPU or sorted according to the usage rate of the memory, and then, according to the result of the sorting, the distribution server is selected according to the occupancy rate of the CPU from small to large and/or the usage rate of the memory from small to large, which is not specifically limited in this application.
Illustratively, the server monitoring platform is connected to the distribution server 1 and the distribution server 2, respectively, the distribution server 1 is connected to the terminal 1, and the server monitoring platform determines that the distribution server 1 is blocked, and then the server monitoring platform switches the distribution server 1 to the distribution server 2, and the distribution server 2 is connected to the terminal 1 to perform service data transmission.

Specifically, if the terminal 1 detects that the data in the cache queue is smaller than the third preset value within 100ms in the preset time period, which indicates that the terminal 1 cannot acquire a large amount of monitoring data from the distribution server, the terminal 1 sends a request to the server monitoring platform, and the server monitoring platform switches the distribution server 1 connected to the terminal 1 to the distribution server 2 after receiving the request sent by the terminal 1.
Under the condition that the distribution server before switching is connected with the terminal, the terminal receives the first I-frame video frame sent by the distribution server after switching, the control terminal is disconnected from the distribution server before switching, and the terminal actively connects the distribution server after switching according to the IP address and the port number of the distribution server after switching, so that the monitoring data sent by the distribution server after switching can be received, and the phenomenon of delayed display or blockage of a display picture is avoided.
